Description Robert Sigler 2013-07-20 10:52:26 EDT
Description of problem:
Unknown. selinux violation popped up while mounting (as sudo su -) an xfs file system at /mnt/f18Root. Running interactive appliations: gnome-terminal. 
SELinux is preventing /usr/sbin/sulogin from using the 'getpgid' accesses on a process.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that sulogin should be allowed getpgid access on processes labeled init_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep sulogin /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Daniel Walsh 2013-07-21 07:13:44 EDT
This looks like you were running sulogin?
Comment 2 Robert Sigler 2013-07-21 09:45:28 EDT
Yes, that is correct. As user, I executed "sudo su -"; then the violation was triggered.
Comment 3 Daniel Walsh 2013-07-22 15:53:55 EDT
sudo su - does not create a process running as sulogin_t.
These are the only processes that can transition to sulogin, and as far as I n
   type_transition initrc_t sulogin_exec_t : process sulogin_t; 
   type_transition openshift_initrc_t sulogin_exec_t : process sulogin_t; 
   type_transition piranha_pulse_t sulogin_exec_t : process sulogin_t; 
   type_transition condor_startd_t sulogin_exec_t : process sulogin_t; 
   type_transition cluster_t sulogin_exec_t : process sulogin_t; 
   type_transition kdumpctl_t sulogin_exec_t : process sulogin_t; 
   type_transition init_t sulogin_exec_t : process sulogin_t; 

So I have no idea how you got sulogin to fire up, this usually only runs in single user mode.

884ae36eb440ed1d178c0abbf155908d04b18b66 allows this in git.
